For some reason i assumed my board would come with a micro SD card from BTT, but it didnt. The only one I had on hand was a newer 128gb card and since it would only format to NTFS or ExFat, the FIRMWARE.bin file would not read by the SKR Pro 1.2.
I tried going into Disk Management in windows, and reformatting that card to 128mb Fat32 and it worked!
I assumed i wouldnt be able to use the card due to the size.
When i get home from work later today, I’ll update this thread with some pics on how to do this. I figure it may help someone in the future.
